I'm not sure. But do I get "extra credit" for simplicity?

Here's what the "slider" widget looks like: http://tinyurl.com/5uvnts

I've put the one from my Catalyst Library on my web page
for you to take a look at. It's written as an object, etc.,
so you won't be able to use it directly. But you are probably
looking for the guts of the code, anyway, and that is all
there. The buttons aren't in 3D, but it does accelerate if
you hold the button down for a second or so. :-)

Just use a slider widget - make it "vertical" and make the x and y
size of the slider really small. It works pretty well, actually.

These are called "spinners". I had one of these, but no longer have
access to the source code (and a quick Google search didn't turn up
anything). They are not too hard to make, I just displayed the images
of up and down arrows in resource/bitmaps in a draw widget and handled
the events. For extra credit, make the button press 3D and have an
acceleration effect when the button is held down.
